Surely, when writing by hand. By I'm writing serializer. In recursive
function serialize(node) key-vals serialization is like

io.write("[", serialize(key), "]", " = ", serialize(value), ",", "\n")

Of course I may change "[" to "[ " but spaces will be added for all
indexed keys and result will be really ugly. So I had to change code and
pass additional silly flag "guy, you're inside indexed key. If your data
first char is '[', write space before writing it".
